A few days ago I had a reader ask me what she could make with some small containers and I immediately suggested she make a sound match game like this one. I didn't have small tupperware like containers but what I did have were old Easter Eggs and lots of things to pop in them.
You will need some containers you can not see into. Various things to put inside like googly eyes, beads, feathers, rocks, small toys, keys... just make sure you have 2 identical sets for each to make a match.
Pop the items in.
I made sure the eggs didn't match up by color but I did that because if one had I was worried my son would try to color match as well.
Start shaking and finding matches.
